The sheet has enough flexibility to adopt the shape of the parabolic steel frame. This frame was constructed from
steel trusses, as shown in Figure 2,
to withstand the effect of wind force and any deformation in the shape of the
parabola that might occur. The two stainless steel sheets were connected to the frame from its edges by sliding them
inside 3 cm grooves at the edge of the frame. Total frame mass including the reflecting surface was approximately 70
kg. This frame configuration allows the testing of different reflecting surfaces. This design can be implemented and
produced in a university workshop and does not require special high technical equipment in producing the reflecting
surface parabola.
